In 2015, the CORESTA E-Cigarette Task Force (changed to E-Vapour Sub-Group in 2016) conducted a study that included testing of commercial electronic cigarette products. This study was referred to as “2015 Aerosol Collaborative Study: Major Constituents” and preliminary results were presented in October 2015. The goal of this work was to compare results from multiple laboratories applying the CORESTA Recommended Method (CRM) No. 81 for aerosol collection and provide a draft analytical method for the determination of nicotine, propylene glycol (PG), glycerin, and water in collected aerosol.

The study results demonstrated that aerosol delivery for the study samples was relatively variable and that the analyte deliveries for a given product tended to be proportional to aerosol collected mass (ACM) deliveries. Evaluation of analyte results normalised to ACM delivery yielded acceptable r&R values. Results from the study control supported the accuracy of the method. Based on these results, the CRM No. 84 - Determination of Glycerin, Propylene Glycol, Water and Nicotine in the Aerosol of E-Cigarettes by Gas Chromatographic Analysis - was approved and published in March 2017.
 

Note: this Technical Report was published in March 2017 and was revised August 2021 to include r&R values for device mass loss (DML) in Table 5.
